Privacy Policy

Last Updated: October 20, 2026

Welcome to BookBoard.co and zLibrary by BookBoard. Your privacy is important to us. This Privacy Policy explains how BookBoard ("we", "us", or "our") collects, uses, stores, protects, and shares information when you visit our website, use our services, or use the zLibrary by BookBoard Android application.

By accessing our website or using our services, you acknowledge that you have read this Privacy Policy. Where applicable law requires consent for particular data processing activities, we will obtain that consent before carrying out those activities.

Please read this Privacy Policy carefully. If you do not agree with the applicable practices described here, you should discontinue using the relevant service.

1. About BookBoard

BookBoard is a digital platform associated with the website BookBoard.co and the Android application zLibrary by BookBoard. Our services may include ebook discovery, digital reading, document access, user-submitted content, publishing-related features, and AI-powered tools.

The services and features available to you may vary by country, application version, account status, and product availability.

Service operator: Appu Raja
Country: India
Website: https://bookboard.co/
Privacy and support contact: [email protected]

BookBoard is a brand and service name. References to BookBoard do not mean that BookBoard is a separately incorporated company. Where required, the identity of the actual legal operator will be provided through the applicable service or official contact information.

The zLibrary by BookBoard application is an independently operated digital reading service. It is not operated by or affiliated with unrelated third-party websites or services merely because they use similar names. The source and licensing status of particular books must be assessed individually.

2. Scope of This Privacy Policy

This Privacy Policy applies to information processed through:

• The BookBoard.co website and its pages.
• The zLibrary by BookBoard Android application.
• User accounts and account-related features.
• Reading, ebook discovery, and document-related features.
• AI-powered features, where available.
• Customer support and communications with us.
• Advertising, analytics, and other integrated services.

This Privacy Policy does not automatically apply to third-party websites, services, applications, or content that we do not control. Those services may have their own privacy policies.

3. Information We May Collect

The information we collect depends on the features you use, the permissions you grant, your interactions with our services, and the third-party technologies integrated into the relevant version.

3.1. Account and Profile Information

If you create an account or sign in, we may collect information such as:

• Name or display name.
• Email address.
• Profile picture, if provided by you or your sign-in provider.
• Authentication identifiers or account IDs.
• Account preferences and settings.
• Other information you voluntarily provide in your profile.

If you sign in using a third-party authentication provider, that provider may process information according to its own privacy policy. The information made available to us depends on the sign-in method and the permissions or choices involved.

3.2. Reading and Content Information

To provide reading and library features, we may process information such as:

• Books or documents you open or choose to access.
• Reading progress, bookmarks, and reading preferences.
• Favourites, saved items, and library organization.
• Search queries and content discovery activity.
• Download or access activity, where recorded by the service.
• Files or content you choose to upload or submit.
• Information necessary to synchronize supported features across devices.

We use this information to operate requested features, remember preferences, maintain reading progress, improve usability, prevent abuse, and troubleshoot problems.

3.3. Files and Documents

Depending on the features you use, the application may let you open, read, import, select, or upload files such as PDF and EPUB documents. Some features may also support other document or media formats.

Files selected for local reading may remain on your device. If you upload a file, synchronize it, submit it to our servers, or use a feature that requires remote processing, the relevant file or its contents may be transmitted to the servers or service providers needed to perform that action.

We do not claim that every file opened locally is uploaded to our servers. Processing depends on the particular feature and the action you choose.

3.4. AI Feature Information

If you use AI-powered features, such as AI assistance, explanations, translations, summaries, question answering, or image-based analysis, we may process the information you submit to provide the requested result.

This information may include:

• Text prompts and questions.
• Text you ask the service to translate, explain, or summarize.
• Images or documents you explicitly submit to an AI feature.
• Relevant contextual information needed to answer your request.
• Technical information needed to operate or troubleshoot the feature.

Depending on the feature and the current implementation, submitted information may be transmitted to third-party AI service providers, such as Google Gemini or OpenAI, for processing.

Do not submit passwords, payment credentials, government identity numbers, confidential business information, or other sensitive information to an AI feature unless the feature specifically requires it and you understand how that information will be processed.

AI-generated responses may be inaccurate, incomplete, or unsuitable for a particular purpose. You are responsible for evaluating generated content before relying on it.

3.5. Device and Technical Information

When you access our website or application, we or our service providers may automatically collect certain technical information, where enabled and permitted by applicable law.

This may include:

• Device manufacturer and model.
• Operating system and version.
• Application version.
• Browser type and version.
• Language and general regional settings.
• IP address and network-related information.
• App launches, feature usage, and diagnostic events.
• Crash reports, performance information, and error logs.
• Identifiers used by analytics, advertising, or security services.

The exact information collected depends on the technologies used, your device settings, applicable permissions, and your choices.

3.6. Communications and Support

If you contact us by email or through a support feature, we may collect your email address, name if provided, message contents, attachments you choose to send, and information necessary to respond to your request.

3.7. Payment and Subscription Information

If paid features, subscriptions, or purchases are offered, payment transactions may be processed by the relevant payment provider or application store.

We may receive limited transaction information, such as a purchase token, product identifier, subscription status, transaction reference, or purchase history, where needed to verify access and manage subscriptions.

We do not intend to collect or store full payment card details when payment processing is handled directly by a third-party payment provider. The provider's own privacy policy and terms also apply.

3.8. Advertising and Analytics Information

If advertising or analytics services are enabled, those services may process information such as advertising identifiers, approximate location inferred from an IP address, ad impressions, interactions, app activity, diagnostic events, and information about the device or application.

Advertising and analytics information may be collected through integrated third-party SDKs, cookies, or similar technologies, depending on the platform and configuration.

4. How We Use Information

We may use information for the following purposes:

• To provide, maintain, and operate our website and application.
• To create accounts and authenticate users.
• To provide ebook discovery, reading, and library features.
• To save reading progress and user preferences.
• To process files or content when you request a relevant feature.

We aim to use personal information only for relevant purposes and according to applicable legal requirements.

5. Books, Copyright, and Content Sources

BookBoard may provide access to digital reading material from different sources, depending on the content and feature involved. These sources may include public-domain material, openly licensed material, content available through third-party sources, content hosted on our own infrastructure, and content submitted or selected by users.

Public-domain status and licensing terms can vary by country, publication, edition, translation, and other circumstances. The availability of a book on the internet does not, by itself, establish that the book is free of copyright restrictions.

We seek to respect applicable copyright and intellectual property rights. If you believe that material accessible through our services infringes your rights, please contact us with sufficient information to identify the material and explain your concern.

Depending on the relevant feature, book metadata, source links, or content may be supplied by third parties. A third-party website or publisher may have separate terms and privacy practices.

Users are responsible for ensuring that they have the necessary rights to upload, distribute, or otherwise submit content to our services.

This Privacy Policy does not grant users any copyright or distribution rights in books, documents, or other content.

5.1. Copyright and Removal Requests

To submit a copyright, licensing, or content-removal request, contact:

Email: [email protected]

Please include the relevant title, URL or content identifier, a description of the rights or concern involved, and sufficient information for us to review the request. We may request additional information where reasonably necessary.

We will review requests and take appropriate action where required by applicable law and our content policies.

6. User-Submitted Content

Some features may allow users to submit text, documents, book descriptions, reviews, feedback, profile information, or other content.

When you submit content, we process it to provide the feature you requested, operate the service, maintain security, enforce our policies, and respond to applicable legal obligations.

Content intended for public display may be visible to other users or visitors. Before publishing content, consider whether it contains private, confidential, personal, or copyrighted information.

Do not upload content that you are not authorized to share or that violates applicable law or the rights of others.

Where content is public, deleting your account may not automatically remove copies already lawfully accessed, independently downloaded, quoted, or otherwise retained by other people. We will handle content under our control in accordance with our policies and applicable legal requirements.

7. Cookies and Similar Technologies

Our website and relevant service providers may use cookies, pixels, local storage, SDKs, and similar technologies to maintain sessions, remember preferences, protect the service, measure usage, and support advertising or analytics.

These technologies may be used for:

• Essential website functionality and security.
• Remembering settings and preferences.
• Understanding website traffic and performance.
• Measuring advertising performance.
• Providing or personalizing advertisements, where enabled and permitted.

You may be able to manage cookies through your browser settings. Blocking certain cookies may affect website functionality.

Where required by law, we will request consent before using non-essential cookies or similar technologies.

8. Third-Party Services and Data Sharing

We do not operate every technology that may be used to provide our services. Certain information may be shared with service providers or third parties when necessary for a disclosed purpose.

Depending on the features enabled, these providers may include:

8.1. Google Services

Google services may be used for authentication, application functionality, analytics, crash reporting, push notifications, advertising, or application distribution.

Relevant services may include Google Play services, Firebase Analytics, Firebase Crashlytics, Firebase Authentication, Firebase Cloud Messaging, Google AdMob, or Google Gemini. Only services actually integrated into the applicable version should be considered active.

Google's privacy information is available at Google Privacy Policy .

8.2. AI Service Providers

If an AI feature uses Google Gemini, OpenAI, or another AI provider, the text, images, documents, or other inputs required to perform your request may be sent to that provider.

The provider processes submitted information under its applicable service terms, privacy documentation, and technical configuration. The processing and retention rules may differ between providers and API products.

You can review the relevant provider information here:

• Google Privacy Policy
• OpenAI Privacy Policy

8.3. Advertising Providers

If advertising is enabled, providers such as Google AdMob or other integrated advertising networks may process device, advertising, usage, and diagnostic information to deliver, measure, or prevent abuse of advertisements, subject to their settings and applicable law.

Depending on the user's location and applicable requirements, advertisements may be personalized or non-personalized. Where required, we will provide the relevant consent and privacy choices.

For Google's advertising-related privacy information, see: Google Advertising Policies and Technologies .

8.4. Analytics, Crash Reporting, and Notifications

Where integrated and enabled, analytics and diagnostic providers may process app events, device information, and crash reports to help us understand performance and improve reliability.

Push-notification services may process device or application identifiers and notification tokens to deliver notifications. You can manage notification permissions through your device settings.

8.5. Other Service Providers

Depending on the current implementation, we may use service providers for hosting, content delivery, file storage, security, email delivery, customer support, payments, or infrastructure.

We may share information with such providers only as reasonably necessary for the relevant services, subject to applicable law and appropriate contractual or technical safeguards.

8.6. Legal and Safety Disclosures

We may disclose information when reasonably necessary to comply with applicable law, respond to valid legal process, protect users, investigate fraud or abuse, enforce our terms, or protect our rights and the security of our services.

8.7. Business Transfers

If our service or relevant assets are involved in a merger, acquisition, restructuring, or transfer, information may be transferred as part of that transaction, subject to applicable legal requirements and appropriate safeguards.

8.8. We Do Not Sell Personal Information

We do not sell personal information in exchange for money. However, certain advertising or analytics activities may involve sharing information with service providers or partners as described in this Privacy Policy. Whether a particular activity is considered a sale or sharing under a specific privacy law depends on the applicable law and the actual processing involved.

9. International Data Processing

Our services may be used by people in different countries. Some service providers may process information on servers located outside your country of residence.

Where information is transferred internationally, we will take measures required by applicable law. The privacy protections and legal requirements in the destination country may differ from those in your country.

10. Data Security

We use reasonable technical and organizational measures designed to protect information against unauthorized access, loss, misuse, alteration, or disclosure.

Depending on the service and information involved, these measures may include HTTPS encryption in transit, access controls, authentication safeguards, restricted administrative access, monitoring, and appropriate hosting or storage protections.

No website, application, network, or storage system can be guaranteed to be completely secure. We therefore cannot guarantee absolute security, but we aim to protect information using safeguards appropriate to the risks and applicable legal requirements.

You should use a strong password where applicable, protect access to your device, and avoid sharing account credentials with others.

11. Data Retention

We retain information only for as long as reasonably necessary for the purposes described in this Privacy Policy, including providing the service, maintaining account functionality, meeting legal obligations, resolving disputes, enforcing agreements, and protecting the security of our services.

Retention periods may vary by information category:

• Account information: retained while your account is active and for a reasonable period afterward where necessary for deletion processing, legal obligations, security, or dispute resolution.
• Reading preferences and progress: retained while needed to provide the relevant reading and synchronization features, unless deleted earlier where supported.
• Support communications: retained for the time needed to respond to requests and maintain appropriate support records.
• Security and diagnostic logs: retained for a limited period appropriate to troubleshooting, fraud prevention, and security needs.
• Transaction records: retained as necessary for purchase verification, accounting, dispute resolution, or legal requirements.
• AI inputs and outputs: handled according to the relevant feature's implementation and the applicable retention practices of the service providers used.

When information is no longer needed, we will take reasonable steps to delete it, anonymize it, or otherwise dispose of it securely, subject to legal obligations, technical limitations, and legitimate security requirements.

12. Account Deletion and Data Deletion

If the service allows you to create an account, you may request deletion of your account and associated personal information.

In-app deletion: If available in your version of the application, open your profile or account settings and select the account deletion option. Follow the instructions shown in the app.

Deletion request by email: You may also contact [email protected] using the email address associated with your account. Include "Account Deletion Request" in the subject line

The online deletion page must be published and functional before this link is used as an official deletion method. Replace this URL if your actual account deletion page uses a different address.

We may need to verify that a request comes from the account holder before processing it. We will not ask you to send your password by email.

After a valid request is processed, we will delete or anonymize personal information associated with the account where required and technically feasible. Some limited information may be retained when required by law or reasonably necessary for security, fraud prevention, legal claims, or transaction records.

If information is retained under a legal exception, we will limit its use to the applicable purpose and retain it only for the necessary period.

Deleting an account may remove access to saved preferences, reading progress, uploaded content, or other account-related features. Please save any information you wish to keep before requesting deletion.

Account deletion does not necessarily delete information that must be retained by a third-party provider under that provider's own legal obligations or that has already been independently retained by others. Where appropriate, you may need to submit a separate request to the relevant provider.

13. Your Privacy Rights and Choices

Depending on your location and applicable law, you may have certain rights regarding your personal information.

These rights may include:

• Requesting access to personal information we hold about you.
• Requesting correction of inaccurate or incomplete information.
• Requesting deletion of personal information, where applicable.
• Withdrawing consent where processing is based on consent.
• Requesting information about certain data processing activities.
• Objecting to or restricting certain processing where the law provides that right.
• Requesting a copy of information where a portability right applies.
• Using available choices to control personalized advertising.
• Submitting a complaint to a competent privacy authority where applicable.

These rights are subject to applicable legal conditions and exceptions. We may need to verify your identity before acting on a request.

To submit a privacy request, contact [email protected] with the subject "Privacy Request".

You may also manage available permissions through your device settings and advertising preferences through the relevant device, application, or service settings.

14. Children's Privacy

Our services are not intended to knowingly collect personal information from children in violation of applicable law. Where a service is used by children, the relevant age requirements, parental consent rules, and applicable child-protection requirements must be followed.

If you are a parent or legal guardian and believe that a child has provided personal information in circumstances where such collection was not permitted, please contact us. We will review the request and take appropriate action as required by applicable law.

Parents and guardians should supervise children's use of online services and consider the privacy implications before children submit personal information, documents, or images to any feature.

15. Permissions Used by the Android Application

Depending on the features available in a particular version, zLibrary by BookBoard may request Android permissions necessary to provide functions you choose to use.

Depending on the implementation, these may include:

• Notifications: to deliver reading reminders, service updates, or other notifications where enabled.
• Files or media access: to let you select, import, open, or manage supported documents where the Android version and feature require access.
• Camera or image access: only if a feature requires you to capture or select an image.
• Network access: to connect to online content, synchronize supported information, retrieve content, or use online services.

This list is illustrative and must be updated to match the permissions actually declared and used by the current application. We do not intend to access a device feature merely because a permission exists; access depends on the implemented functionality and applicable permissions.

You can review or revoke available permissions through your Android device settings. Revoking a permission may limit the functionality that depends on it.

16. Advertising Choices

If the application or website displays advertisements, certain advertising providers may use information to select, deliver, measure, or limit advertisements, subject to applicable law and your available choices.

Depending on your region and the technologies used, you may be presented with advertising consent choices. You may also be able to change relevant preferences in your device or service settings.

Blocking personalized advertising does not necessarily mean that all advertisements will disappear. Non-personalized or contextual advertisements may still be displayed where permitted.

17. Third-Party Websites and Links

Our website or application may contain links to third-party websites, ebook sources, publishers, service providers, or other external resources.

We do not control the privacy practices, security, content, or availability of third-party services. Visiting an external website or using an external service is subject to that provider's own terms and privacy policy.

We encourage users to review the privacy policy of any third-party service before submitting personal information to it.

18. Automated Processing and Security Measures

We and our service providers may use automated systems to perform functions such as troubleshooting, analytics, content organization, spam detection, abuse prevention, and application security.

If a security feature detects a possible integrity issue or unauthorized modification, limited technical information may be processed to investigate or protect the service. Any such collection must match the actual security features implemented in the app.

Automated processing may occasionally produce errors. Where required by applicable law, you may contact us to ask about relevant processing or request a review of an issue.

19. Legal Basis for Processing

Where applicable privacy law requires a legal basis for processing, we may process personal information on one or more of the following bases, as appropriate to the activity:

• To provide a service or perform a contract with you.
• To comply with legal obligations.
• With your consent, where consent is required or relied upon.
• For legitimate interests permitted by applicable law, such as service security and improvement.
• To establish, exercise, or defend legal claims where permitted.

The applicable basis depends on the information and processing activity. Where processing relies on consent, you may withdraw that consent subject to applicable law.

20. Changes to This Privacy Policy

We may update this Privacy Policy to reflect changes in our services, technologies, legal requirements, or data-handling practices.

When we make changes, we will update the "Last Updated" date at the top of this page. Where required by law, we will provide additional notice or request consent before implementing relevant changes.

We encourage you to review this page periodically to stay informed about how information is handled.
